Application filed March 30, 1886. Serial No. 197,177. (No rnodel.)

To aZZ whom, it may concern.-

Be it known that I, FRIEDRICH LINK, a subject of the Emperor of Germany, residing at the city of New Orleans, in the parish of Orleans and State of Louisiana, have invented a a. new and useful Improvement in a Lever- Catch for Fastening Double Doors, of which the following is a specification.

My invention relates to fastenings for double doors for armories, book-cases, and dwellings, and for all double doors that open and shut.

The object of myimprovenientis to provide a secure fastening for double doors, the same being adjusted to facing at top and bottom of door-frame, which is readily adj nsted and economical and made of metal. I attain these objects by the mechanism illustrated in the accompanying drawings.

Figure 1 represents a perspective view of my lever-catch and fastening for double doors. Letter A represents a lever-catch; B, center pivot; G, spiral spring; D, plate.

Fig. 2 is a representation of a cabinet with lever-catch attached.

I am aware that prior to my invention double doors were fastened by hooks and bolts.

In my improvement the left-hand door is first closed,and at bottom and top of said door a cavity is made, being in proportion to weight of door. Under bottom and top of left-hand door a catch is forced up and down, which securely fastens both left and right hand door when right-hand door is closed, preventing the door from opening, except by pressure when entrance through double doors is desired.

I claim as my invention.

The vertically-moving bolt attached to the vibrating pivoted lever and arranged to extend below the bottom of the door, in combination with a. vertically-moving bolt attached to the other end of the pivoted lever and located below a hole made in the bottom of the closed door, substantially as described.

FRIEDRICH LINK.
